Abstract

According to various embodiments, a semiconductor structure may include: a first source/drain region and a second source/drain region; a body region disposed between the first source/drain region and the second source/drain region, the body region including a core region and at least one edge region at least partially surrounding the core region; a dielectric region next to the body region and configured to limit a current flow through the body region in a width direction of the body region, wherein the at least one edge region is arranged between the core region and the dielectric region; and a gate structure configured to control the body region; wherein the gate structure is configured to provide a first threshold voltage for the core region of the body region and a second threshold voltage for the at least one edge region of the body region, wherein the first threshold voltage is less than or equal to the second threshold voltage.
